Question

Solve , 2x- 3y is equal to 12 , x +2y is equal to 1 by cross multiplicatio​

Answer 1

Answer:

hope it is helpful to you

Answer 2

2x - 3y = 12

2x - 3y - 12 = 0

x + 2y = 1

x + 2y - 1 = 0

x = b1c2 - b2c1 = -3×-1 - 2×-12 = 3 + 24 = 27

a1b2 - a2b1 2×2 - 1×-3 4 + 3 7

y = c1a2 - c2a1 = -12×1 - 2×-1 = -12+2 = -10

a1b2 - a2b1 2×2 - 1×-3 4 + 3 7

Hope it helps!!

Thank you ✌️
